CELLULOSE NITRATE OR NITRO CELLULOSE A highly combustible and explosive compound produced by
the reaction of nitric acid with a cellulose material.
CELLULOSE NITRATE PLASTIC (PYROXYLIN) Any plastic substance, materials or compound having
cellulose nitrate (nitro cellulose) as base.
COMBUSTIBLE, FLAMMABLE OR INFLAMMABLE Descriptive of materials that are easily set on fire.
COMBUSTIBLE FIBER Any readily ignitable and free burning fiber such as cotton, oakum, rags, waste cloth,
waste paper, kapok, hay, straw, Spanish moss, excelsior and other similar materials commonly used in
commerce.
COMBUSTIBLE LIQUID Any liquid having a flash point at or above 37.8o C (100o F).
CORROSIVE LIQUID Any liquid which causes fire when in contact with organic matter or with certain
chemicals.
CURTAIN BOARD A vertical panel of non-combustible or fire resistive materials attached to and extending
below the bottom chord of the roof trusses, to divide the underside of the roof into separate compartments
so that heat and smoke will be directed upwards to a roof vent.
CRYOGENIC Descriptive of any material which by its nature or as a result of its reaction with other elements
produces a rapid drop in temperature of the immediate surroundings.
DAMPER A normally open device installed inside an air duct system which automatically closes to restrict
the passage of smoke or fire.
DISTILLATION The process of first raising the temperature in separate the more volatile from the less
volatile parts and then cooling and condensing the resulting vapor so as to produce a nearly purified
substance.
DUCT SYSTEM A continuous passageway for the transmission of air.
DUST A finely powdered substance which, when mixed with air in the proper proportion and ignited will
cause an explosion.
ELECTRICAL ARC An extremely hot luminous bridge formed by passage of an electric current across a
space between two conductors or terminals due to the incandescence of the conducting vapor.
EMBER A hot piece or lump that remains after a material has partially burned, and is still oxidizing without
the manifestation of flames.
FINISHES Materials used as final coating of a surface for ornamental or protective purposes.
FIRE The active principle of burning, characterized by the heat and light of combustion.
FIRE TRAP A building unsafe in case of fire because it will burn easily or because it lacks adequate exits or
fire escapes.
FIRE ALARM Any visual or audible signal produced by a device or system to warm the occupants of the
building or fire fighting elements of the presence or danger of fire to enable them to undertake immediate
action to save life and property and to suppress the fire.
FIRE DOOR A fire resistive door prescribed for openings in fire separation walls or partitions.
FIRE HAZARD Any condition or act which increases or may cause an increase in the probability of the
occurrence of fire, or which may obstruct, delay, hinder or interfere with fire fighting operations and the
safeguarding of life and property.
FIRE LANE The portion of a roadway or publicway that should be kept opened and unobstructed at all times
for the expedient operation of fire fighting units.
FIRE PROTECTIVE AND FIRE SAFETY DEVICE Any device intended for the protection of buildings or
persons to include but not limited to built-in protection system such as sprinklers and other automatic
extinguishing system, detectors for heat, smoke and combustion products and other warning system
components, personal protective equipment such as fire
